Safety & Foundations
- rm and rm -r are permanent – there is no Recycle Bin on the command line; always double-check the filename and folder before running a delete command
- Never run rm -r or chmod changes on real hospital system folders without a second person’s review – a single mistyped path can affect live patient-facing systems
- Avoid running sudo commands unless you fully understand what they do; running commands as an administrator affects the whole system, not just your project
- When downloading with curl or wget, only pull from trusted, approved sources – never paste real patient data into a URL or API call
